This bulb with the consumption of 6 watts, the luminosity of a normal 40-watt light bulb in every case. Of course, one has no standard bulb with this cold Weißlicht.Somit limited the comparison only on the brightness. The size corresponds to the conventional light bulbs, so they can be used in lamps with corresponding covers. I have them mounted in Treppenkaus where it is thus at least as bright as before with 40 watt bulbs. The white light is of course nothing for living rooms or places where you want to stay longer. As the warm tone for the coziness missing. But staircase, garage, basement, these are places where this power-saving lighting fully served its purpose. This value for money so I can give an unqualified recommendation.
